Its 273V maximum clamping voltage at 5.5A peak pulse current (10/1000µs waveform) defines the protection ceiling — downstream equipment must survive that peak without damage. Rated for 1500W peak pulse power, this part handles substantial surge energy in a through-hole axial package. ## Active production — no obsolescence concern The through-hole axial package (B, Axial) is a mature, widely stocked form factor. Lead time is confirmed at quote time against the BOM quantity — typical for active Microchip TVS devices in this package family.","metaTitle":"1N6173A Zener TVS Diode – 273V Clamp, 1500W","metaDescription":"1N6173A Zener TVS diode from Microchip. 273V clamping at 5.5A, 1500W peak pulse.

For a rail that sits at 152V nominal, the 190V breakdown provides adequate margin — the TVS stays off during normal operation and only clamps during overvoltage events."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6173A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6173A when reusing this data.
